Deprecated

• ServiceAttr() function in go.opentelemetry.io/contrib/instrumentation/github.com/aws/aws-sdk-go-v2/otelaws is deprecated. Use MethodAttr() instead, as rpc.service has been merged into rpc.method in semantic conventions v1.39.0. (Bump to semconv/v1.39.0 #8404)
• OperationAttr() function in go.opentelemetry.io/contrib/instrumentation/github.com/aws/aws-sdk-go-v2/otelaws is deprecated. Use MethodAttr() instead, as rpc.service has been merged into rpc.method in semantic conventions v1.39.0. (Bump to semconv/v1.39.0 #8404)

Removed

• The deprecated DefaultClient, Get, Head, Post, and PostForm in go.opentelemetry.io/contrib/instrumentation/net/http/otelhttp. Use a custom *http.Client with otelhttp.NewTransport(http.DefaultTransport) instead. (Remove the deprecated otelhttp Client #8266)
• The deprecated WithPublicEndpoint in go.opentelemetry.io/contrib/instrumentation/net/http/otelhttp. Use WithPublicEndpointFn instead. (Remove the deprecated WithPublicEndpoint from otelhttp #8267)
• The deprecated WithRouteTag in go.opentelemetry.io/contrib/instrumentation/net/http/otelhttp. The route is already added automatically for spans. For metrics, the alternative is to use the WithMetricAttributesFn option. (Remove the deprecated WithRouteTag option in otelhttp #8268)
